BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to consumer electronics, and more particularly toa method and apparatus for determining location of a control device inan area and controlling other devices based on the determined location.

2. Description of the Related Art

For many consumer electronic (CE) products, various types of remotecontrols exist to control the specific CE device. Many CE devices have aone-to-one correspondence of remote control to CE device. Many CEdevices, however, have a remote control device that can control morethan one CE device. FIG. 1 illustrates this type of control device. Inthe example illustrated in FIG. 1, remote control 1 (RC1) 105, iscapable of controlling television 1 (TV1) 125 and videocassette recorder1 (VCR1) 130. RC2 110 is capable of controlling TV2 135 and digitalversatile disc 1 (DVD1) 140. Also illustrated in FIG. 1, RC3 115 onlycontrols stereo 1 150, and RC4 120 is capable of only controlling TV3145.

In view of the many CE products purchased by users, it becomes apparentthat a typical modern household may contain a plurality of RC devicesfor all the CE products. Therefore, universal RCs were developed tocontrol many CE products and replace the many associated remotecontrols. FIG. 2 illustrates universal RC (URC) 200. In the exampleillustrated in FIG. 2, URC 200 replaces RC1 105, RC2 110, RC3 115, andRC4 120, which are illustrated in FIG. 1. A device such as URC200,however, needs to either be programmed beforehand with control codeinformation for each specific device, or programmed/trained for each CEproduct that it is to control. Further, as illustrated in FIG. 2A,multiple URCs may each control a group of CE devices. FIG. 2Aillustrates three URCs (URC1 200, URC2 250, and URC3 260) that controlthree groups of CE products.

With either a single URC or group of URCs, the control codes aretypically transmitted from the URC via radio frequency (RF) or infrared(IR) signals. Also, the various CE products are typically maintained inseparate rooms. With some transmission means, for example RF,penetration through a wall may be a capability. For IR transmissionsignals, however, the control codes are mainly limited to transmissionwithin a single room or boundary (i.e., bounded by a wall). Also, RFtransmitted signals are typically limited to a specific distance.Therefore, whether a single URC or group of URCs are kept to control aplurality of CE products, the complexity still exists for many users ofknowing which remote control controls which group, or which controlmechanism (such as buttons on a remote control) control which devices,and in which specific room.

DETAILED DESCRIPTION OF THE INVENTION

The invention generally relates to a method and apparatus for locating adevice in a dwelling or enclosed space. Referring to the figures,exemplary embodiments of the invention will now be described. Theexemplary embodiments are provided to illustrate the invention andshould not be construed as limiting the scope of the invention.

FIG. 3 illustrates a typical environment 300 having four separaterooms/areas. A user of consumer electronic (CE) products, such astelevision 1 (TV1) 125, video cassette recorder 1 (CVR1) 130, (containedin room/area 1), cable decoder 205, TV2 135, digital versatile disk 1(DVD1) 140 (contained in room/area 2), TV3 145, stereo 1 150 (containedin room/area 3), and TV4 305, VCR2 310, and satellite receiver 1 210(contained in room/area 4) would need either a sophisticated universalremote control (URC), a plurality of individual remote controls (RC) ormultiple URCs to control the plurality of CE products.

If a user has similar CE products, for example, if TV1 125 and TV2 135are the same make and model, one RC can control both TV1 125 and TV2135. A problem with this, however, is if a user in room 1 is using TV1125 and another user in room 2 is using TV2 135, when either user 1 or 2decides to enter a command on an RC for the specific TV they are using,the other TV could possibly be affected. This is because each RC doesnot have information regarding a specific location and/or device withina specific location.

FIG. 4 illustrates an embodiment of the invention including system 400.System 400 comprises transceiver 430, processor 420, memory 425,transmission medium 440, RC device 450, transmitters 405-408, and aplurality of CE devices (TV1 125, VCR1 130, TV2 135, DVD1 140, TV3 145,stereo 1 150, TV4 305, satellite receiver 1 210, VCR2 320) in a singleenvironment, such as a dwelling, a vehicle, a building, etc. It shouldbe noted that other CE devices could be included in system 400 withoutvarying embodiments of the invention.

In one embodiment of the invention, transceiver 430 comprises Bluetooth™standard (specification of the Bluetooth system version 1.1, Feb. 22,2001) receiver and a Bluetooth™ standard transmitter. One should note,however, that other technologies could be used for transceiver 430without varying from the scope of the invention. Transceiver 430 is usedto transmit control commands to the plurality of CE devices in system400, and receive control commands from RC device 450. Transmitter405-408 transmits a location code that is specific to each area or roomin system 400.

Transmitter 405 may be a limited radio frequency (RF) transmitter, aninfrared (IR) bug, or similar transmission device. Transmission medium440 is coupled to the plurality of CE devices in each area/room insystem 400. Transmission median 440 may be coupled to a transmitter ineach area/room, coupled directly to each CE device in each area/room ormay be a wireless connection to a transceiver located in each area/room.

Transmission median 440 allows control commands to be carried out on theplurality of CE devices. Transmission median 440 may be comprised of awireless network comprising IEEE 802.11 Standard (802.11, 1999/8802-11(International Organization for Standardization/InternationalElectrotechnical Commission) (ISO/IEC) 8802-11:1999) IEEE Standard forInformation Technology—(Local Area Network/Metropolitan Area Network)LAN/MAN—Specific requirements—Part 11: Wireless LAN Medium AccessControl (MAC) and Physical Layer (PHY) specifications 1999), IEEE1394standard (1394-1995 IEEE Standard for a High Performance SerialBus—Firewire 1995) technology, Ethernet technology, or other means forcoupling processor 420 to the plurality of CE devices, such aselectrical wiring (e.g., X10), cellular technology, etc.

FIG. 5 illustrates an embodiment of the invention having RC device 450.In one embodiment of the invention, RC device 450 comprises receiver 505and transmitter 510. RC device 450 may comprise a user interface, suchas push buttons, flat touch buttons, a touch screen, keyboard, etc. Inone embodiment of the invention, RC device 450 may be a personal digitalassistant (PDA). Receiver 505 receives control codes from transmitters405-408. Each one of transmitters 405-408 transmits a specific coderepresenting a specific area/room in which transmitter 405-408 islocated. The location code transmitted by transmitters 405-408 can be asimple representation, such as a binary representation of a digit (e.g.,room 1 is represented by “01”, room 2 is represented by “02”, etc.).When a user wishes to control the CE devices in room/area 1 (TV1 125 andVCR1 130), and is in room/area 1, RC device 450 by receiving the controlcode transmitted by transmitter 405 will know that it is located in room1.

When a user selects to control TV1 125 via RC device 450, a user willselect a command via the user interface on RC device 450 (e.g., TV on,channel number, volume, etc.). RC device 450 forms a packet includingthe location code received from transmitter 405 and the control code forthe specific command that the user wants to occur. The packet of data isthen transmitted and received by transceiver 430.

Processor 420, having memory 425, includes control command codes foreach of the plurality of CE devices in system 400. The control codes foreach specific CE device are stored in memory 425. Processor 420 may be adevice such as a personal computer (PC) system, set top box (STB), etc.In one embodiment of the invention, control codes for specific CEdevices are downloadable either via a network connection (e.g., theInternet), compact disk read-only memory (CD-ROM), telephone lines via amodem, communicated by a universal plug-and-play technology (e.g., CEBusHomePnP™) or learned/trained by a device such as a URC.

For each room/area, a user can set up which CE devices are to be locatedwithin the room/area on processor 420. Therefore, when processor 420receives the packet from remote controller device 450 comprisinglocation code and control command code, processor 420 will transmit backto transceiver 430 via appropriate control command for the CE deviceswithin the room/area. When a user decides to change rooms/areas, theuser travels to the desired area/room with RC device 450.

While the user is in the next desired room/area, one of transmitters405-408 that is continuously transmitting a location code, will give thelocation code information to the RC device 450. Therefore, remotecontroller device 450 will know exactly which room/area it is locatedin. Thus, when a user selects a specific CE control command to execute,the new room/area code and data packet containing the control commandthat the user wishes to execute is sent to transceiver 430. Processor420, based on the location code received, will know which specific CEdevice is to be controlled.

FIG. 6 illustrates an embodiment of the invention having RC device 600.RC device 600 is similar to RC device 450, however, RC device 600comprises microphone 610 and voice processor 620. RC device 600 receivesuser input via microphone 610. Voice processor 620 converts voicecommands received through microphone 610 into a command packet.Therefore, a user can input desired control commands by speakingcommands such as “TV on,” “VCR off,” “Volume up,” etc. RC 610 thencombines location code and control command data into a packet, which istransmitted via transmitter 510 to transceiver 430.

In one embodiment of the invention, receiver 505 and RC device 450 or600 may use global positioning satellite (GPS) or cellular technology todetermine location in an area/room. In this embodiment, transmitters405-408 are not necessary since receiver 505 will receive the locationinformation from outside of the system 400. In this embodiment of theinvention, processor 420 will be more sophisticated in determining thelocation from the transmitted location data that is received bytransceiver 430.

Additional set-up information will be required for information regardingspecific rooms/areas for this embodiment using GPS technology. Forexample, for an embodiment including a GPS receiver within the RCdevice, location codes may need to be transmitted to transceiver 430 tobe processed by processor 420 for four locations of an area/room (e.g.,four corners). In this case, a user can transmit the locationinformation (latitude, longitude, altitude, as received on the GPSreceiver) from four points in the room, which are then stored in memory425 within processor 420. The user would then repeat the same sequencefor each room. The processor would then be able to determine whichroom/area a user was located in via the received location information(e.g., latitude, longitude, and altitude). For adjoining rooms/areas,more locations within the room may need to be transmitted due to theproximity of the location information. In larger environments, such as amansion, a RC device having a GPS receiver can eliminate the cost ofhaving a plethora of location transmitters. Also, in certain areas wheresatellite reception may not be strong, additional equipment may benecessary, such as exterior antenna or dish.

In one embodiment of the invention, an additional GPS receiver is fixedat the location of processor 420. A reading takes place at the GPSreceiver co-located at processor 420 at the same time the locationinformation is received by receiver 505. The difference in locationinformation (i.e., altitude, latitude and longitude) between the fixedGPS receiver and receiver 505 will yield a relative difference. Thisrelative difference remains constant independent of any inaccuracy ofthe absolute location. Therefore, the determination of the boundary/roomwill be highly accurate.

FIG. 7 illustrates how CE device commands may be organized/stored via aspecific area/room hierarchy according to one embodiment of theinvention. As illustrated in FIG. 7, each specific area/room iscomprised of a CE device or devices. Each CE device(s) is associatedwith specific command codes for that CE specific device.

In one embodiment of the invention, a user may program processor 420 inable to command a specific sequence of commanded events. For example, afirst user may typically set the CE devices located in room 4 asfollows: TV4 on, volume set to {fraction (5/10)}, channel set to 29,VCR2 320 set to off, and satellite receiver 1 210 set to on. Therefore,in this embodiment of the invention a user may select a favorite settingto be executed. In this embodiment of the invention, the remote controldevice 450 or 600 will be used to enter the specific command for thefavorite sequences to occur. In one embodiment of the invention, thesequence of events can be organized/stored in a hierarchy on processor420 as illustrated in FIG. 8. In one embodiment of the invention, thelast entered sequence of events (e.g., volume setting, tone setting,device on/off, etc.) can be selected as a new sequence of events to beperformed.

In one embodiment of the invention, the user can store favoritesequences on processor 420 via a user interface. A user interface may besuch as a keyboard, a pointing device, or a voice activated processingsystem. For each location, a plurality of users can enter a plurality offavorite sequences. In one embodiment of the invention, a user isprompted to enter information for a CE device as a new device is addedto the system. Also, if a device is moved from a room, the informationfor that device is removed from the room/area hierarchy and istemporarily stored in memory in case the device is connected withinanother room/area. If a CE device is moved, the user will be promptedwhether a similar sequence is desired, allowing for different CE deviceswithin the new room/area.

In one embodiment of the invention, restrictions for specific CE device“on/off” time limitations may be entered by a user with specialprivileges. A user with special privileges, such a parent, can limitcertain times that specific CE devices may be used by specific users.The user with special privileges, can also set channel restrictions ontelevision/satellite receivers, volume restrictions on certain CEdevices, and time restrictions for which devices in which rooms may becommanded or turned off/on. A user with special privileges can be knownby entering a certain password code, which may be a sequence of numbers,through RC device 450 or 600. Therefore, each user can have a separatepassword code for the same RC device.

Other devices that have remote control capabilities, such as curtains,fire places, ceiling fans, lights, dimmers, etc. may be controlled fromremote controller device 450 or 600. Therefore, a user can program afavorite sequence of events for each specific room, which can includesetting room moods, and preferences. For example, a user can select forroom/area 1 to have the lights dimmed to half intensity, curtainsclosed, stereo volume set to low, TV turned on and set to a specificchannel, etc. In one embodiment of the invention, a favorite sequence ofevents can be varied based on the time of day. For example, a daytimesequence may open curtains, turn off lights, and set devices and volumesto a day-time level; a night-time sequence may open curtains, turn onlights, and set device and volumes to a night-time level. Also, afavorite sequence can change with the time of year, such as winterversus summer settings.

When a person with special privileges, such as a parent, programsprocessor 420 for a user without special privileges, such as a child,the parent can actually control which rooms, which devices, what times,what volume, etc. that can be accessed by the child. For example, if aparent did not want a child to use channels 20-69 on a satellitereceiver in room/area 4 (as illustrated in system 400), when the childenters room/area 4 and enters a channel in the restricted zone, the RCdevice 450 or 600 can indicate to the child that access is restricted.

Also if a child is not allowed to watch TV in rooms/areas 1-3 between acertain set of hours, when the RC device 450 or 600 is located inrooms/areas 1, 2 or 3, when the child enters the command to turn the TVon, a “restricted” notification will be made through the RC device. Therestricted notification, may be a flashing light, a text note, a voicecommand through a small speaker, or a tone. In one embodiment of theinvention, the notification can be made through a stereo device, atelevision, sequence of light flashes from lamps, etc.

FIG. 9 illustrates how the embodiment of the invention can behierarchically organized/stored to give restrictions to specific usersin certain locations. It should be noted that a user with specialprivileges can program processor 420 with restrictions/accesses forspecific users in specific locations, and view the programmedrestrictions/accesses for each user in specific locations, and favoritesequences (as illustrated in FIG. 8) on a monitor device coupled withprocessor 420. Another embodiment of the invention, the specificprogrammed restrictions/accesses/favorites can be viewed on a RC device,such as a PDA.

In one embodiment of the invention, a user can circumvent the specificlocation that they are located within by entering a command via RCdevice 450 or 600. By using this type of command, other control commandsmay be activated in other areas/rooms. For example, if a user travels toa first room/area, and forgot to turn off CE devices (e.g., lights, TV,VCR, cable decoder, etc.) in a room/area at a good distance from thecurrent location, the user can override the received location code andenter the location code and sequence and/or commands to be executed inthe other room/area. In one embodiment of the invention, devices inother locations can be controlled by a favorite sequence of events. Forexample, a user may have a “bedtime” sequence that turns off all thelights, devices, turns on the alarm system, shuts the garage door, etc.

FIG. 10 illustrates a block diagram of an embodiment of the invention.Process 1000 begins with block 1010 where a user selects a controlfunction on a RC device. Block 1020 then determines the transmittedlocation code from a transmitter, such as transmitters 405-408illustrated in FIG. 4. In block 1030, the remote controlled device formsa transmission packet including the location code and control code forthe selected function that the user has selected. In block 1040, thetransmission packet is transmitted through the remote control device toa transceiver, such as transceiver 430.

Block 1045 receives the transmission packet at a transceiver, such astransceiver 430. In block 1050, based on the received location code andcommand code in the received transmission packet, the specific devicecontrol code is determined for the specific location.

Block 1060 then transmits the device specific control code to thespecific location and to the specific device located in the location. Inblock 1070, the device specific control code is received. The devicespecific control code can be received either at the specific CE device,or a receiver/transmitter device located within the specific location.In block 1080, the user control function that was selected is performedon the CE device.

FIG. 11 illustrates a block diagram of an embodiment of the inventionhaving process 1100. Process 1100 begins with block 1110 where a usercan enter a specific password code. Blocks 1010-1045 are the same aspreviously discussed in reference to process 1000 illustrated in FIG.10.

After block 1045 has completed, process 1100 continues with block 1120where the access/restriction for location and specific CE devices forthe specific user is determined. Block 1130 determines whether thespecific user has access (privilege) or is restricted from completingthe selected control function. If block 1130 determines that the userdoes have access, then process 1100 continues with block 1050. If block1130 determines that the user does not have access (is restricted),process 1100 continues with block 1160. Block 1160 informs the user ofthe denied or restricted access for the specific entered command for thespecific location.

In block 150, the device specific control code is determined. Process1100 continues with block 1060-1080 as previously discussed in referenceto process 1000 illustrated in FIG. 10. After block 1080 is complete,process 1100 continues with block 1140, where it is determined whetherall the functions have completed for the selected control function ofthe user (for sequences of control functions, e.g., user 1's favoritesin location 1, etc.). If block 1140 determines that all functions arecomplete, process 1100 completes with block 1160. If block 1140determines that all control functions are not complete, process 1100continues with block 1150, which determines the next control code in thesequence. Process 1100 then continues with block 1060 and the processgroups until all control codes are performed in the selected sequence.

The above embodiments can also be stored on a device or medium and readby a machine to perform instructions. The device or median may include asolid-state memory device and/or a rotating magnetic or optical disk.The device or median may be distributed when partitions of instructionshave been separated into different machines, such as across aninterconnection of computers.
